Card Trivia:Castle of Dark Illusions
- The kanji (闇) on the ring on the front of the castle translates to "darkness", reflecting this card's DARK Attribute.
- This card is one of the few monsters whose ATK or DEF is not divisible by 50. Others include "Sword Arm of Dragon", "Dark Chimera", "Reaper of the Cards", "King of Yamimakai", "Barox", and "Number S39: Utopia Prime". Notably, PaniK had all of these cards in his Deck (except for "Number S39: Utopia Prime" (who was used by Yuma Tsukumo) and "Sword Arm of Dragon"), and they were all present in his Duel with Yugi Muto.
